The Lowdown

Alright, grab your board and wax. Rusty here, having a good look at what’s coming up for Jaconé.

Right now, we’ve got a bit of a flat start to the period. There’s nothing worth paddling out for on Tuesday the 15th or Wednesday the 16th, despite some small swell showing up – the wind is just all wrong, blowing onshore and making a mess of it. It’s going to feel like one of those waiting games for a couple days.

We finally get a sniff of decent conditions on Thursday morning the 17th. The swell builds to about 5ft out of the S, the wind goes light and cross-offshore from the E, and we get clean lines. There’s moderate energy in the water (751 combined energy), but with a period around 11 seconds, it should have a little bit of push. It’s shaping up to be clean, but don't expect perfection. The afternoon isn't as good, with the energy dropping slightly and more cross-off wind.

Friday the 18th is still rideable but the wind strengthens, making it harder to get a smooth wave. Saturday the 19th blows harder with a fresh offshore breeze from the ENE, so the surf will be small and blown out. You’d be better off sitting that one out.

Now, Sunday the 20th is a fun day on the menu. Morning conditions see the swell dropping to about 4ft, but it switches direction to the E with a short period of 7 seconds. It's not powerful, but the combined energy is moderate (395), and the wind is a light offshore from the NE – clean, glassy peaks. That’s the kind of afternoon session where you can find a few long, cruisy waves.

The middle of the week from Monday 21st to Wednesday 23rd goes quiet again. Small 2ft to 3ft swells hanging around, and while there are pockets of glassy wind (especially on Monday morning and Wednesday afternoon), the energy is weak (all values under 143). Gaps between sets will be felt. You’ll be scratching for waves, but the water is about normal for the time of year.

The real standout begins from the morning of Thursday the 25th of September. A solid S swell with a long period of 12 seconds pushes in at about 5ft, combined energy of 624, and light offshore winds from the NE. That’s what we call a proper clean, solid morning. The following days, the quality holds. On Saturday the 26th, the morning brings about 4ft from the S with a very long 13-second period and combined energy of 806. This is prime groundswell – perfect for this beach. The wind stays offshore and light, so expect nice shapes with a bit of wait between sets.

We hit the climax early on Tuesday the 29th of September. This is the one to circle on the calendar. A solid 6ft SSW swell with a long period of 12 seconds hits hard (1028 combined energy – strong energy), and the wind is a light offshore from the NNE. This is excellent surf for experienced surfers. The water temperature is a comfortable 73°F. It’s going to be a heavy, clean, powerful day out at Jaconé, but beginners might want to hang back – 6ft with that period will have some push behind it.

Wednesday the 30th still keeps up the quality, with a 5ft S swell, light offshore winds from the ENE, and solid 511 combined energy. Clean, punchy waves to close out the month.

The real highlight across the whole period has to be Tuesday the 29th of September – the biggest, most powerful, cleanest swell of the forecast window. If you’re experienced, that’s the morning. Second best is the morning of Saturday the 26th for that silky, long-period groundswell and clean conditions.

Keep your eyes on the horizon, and don’t sleep on that end of September run.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
